Gary Stills is the first to acknowledge that he hasn't made the kind of impact on the Ravens' defense that he had envisioned. A pass- rushing linebacker who once collected 7 1/2 sacks during a three- year span for the Kansas City Chiefs, Stills has just two tackles, a forced fumble and a fumble recovery this season.

Although Stills amassed 79 tackles and 7 1/2 sacks in a three- year span from 2002 to 2004, Stills could not crack the Chiefs' starting linebacking corps. But Stills cherished his time in Kansas City, where he absorbed lessons from Marvcus Patton and the late Derrick Thomas.

Notes -- Linebacker Dan Cody (knee) and running back Musa Smith (neck) will not play in tomorrow's game. Right guard Keydrick Vincent (groin) and linebacker Dennis Haley (ankle) were upgraded to probable. Tight end Daniel Wilcox (hamstring) is still questionable, and cornerback Ronnie Prude (illness) is still probable. ... Matt Stover is one field goal away from joining an exclusive club of kickers who have made 400 field goals. Stover, who has 399 in his 17th year, would join Gary Anderson (538), Morten Andersen (537) and John Carney (409). ... A flu bug has spread among the Ravens, including [Brian Billick]. "I've got more drugs in me than the entire Haight- Ashbury district in San Francisco," he joked. ... The Ravens had two players in for tryouts: receiver Alex Bannister (a former special teams ace for the Seattle Seahawks) and punter John Torp.
